Eonums is a simple module providing conversion between normal
integer numbers and the corresponding textual expression in the
Esperano language.
It was mainly developped in order to explore the regularity of
Esperanto expressions for big integer numbers.

Names for 10**k (k = 6, 9, 12, …) like “miliono” (10**6) or
“miliardo” (10**9) are chosen from the so-called “Longa Skalo”
as described on this page about
big numbers
(in Esperanto).

The integer numbers eonums can convert to or from such Esperanto
expressions can be arbitrarily large, but are limited in practice
by the largest number for which there is a name in Esperanto (on
the “Longa Skalo”)”, which is, on the previous page, 10**63
(dekiliardo). Hence, the largest integer you can handle with this
module is 10**66 - 1. (This module makes no attempt to extend the
Esperanto naming rules by introducing names like “undekiliono”,
“undekiliardo”, “dudekiliono” etc.)

This module can be fully translated automatically to Python 3.0
using its migration tool named 2to3.
